If I post oce on the forum, then I'm happy for people to do anything they like with it. the only thing I don't like is people posting the game I post as their own creation on the app store, as long as they change the graphics and sounds, and try to at least add something to the code, then I'm happy. A credit is always nice too.
I'd also like to think that if someone took my code, added more graphics and then made $50,000 on it, then they'd at least send me $10,000 to say thanks.
